When to specify heavy-duty pavers? In practice, heavy vehicular traffic is thought of as a high frequency of fully loaded tractor-trailers typically found on a municipal street or road. A more precise definition would say "high volumes of heavy vehicles representing trucks or combination vehicles having three, four or more loaded axles with daily equivalent single axle loads (ESAL) of 250 or greater". The National Stone Association's FLEXIBLE PAVEMENT DESIGN GUIDE FOR ROADS AND STREETS is a good reference for determining whether your project has heavy vehicular traffic. In general terms, occasional passes of a garbage truck or tractor-trailer does not constitute heavy vehicular traffic. If you determine that you have heavy vehicular traffic, you will need to design your paving system to accommodate the traffic, usually requiring a thicker, aggregate base equivalent. (See BIA’s VEHICULAR DESIGN GUIDE) In your system, you will need to specify a heavy vehicular paver that meets ASTM C 1272 standards. There are two types of heavy vehicular pavers, Type R and Type F. Type R pavers are 2-1/4" thick and are used when the design calls for a rigid sub-base of concrete or asphalt and a setting bed of mortar or bituminous. Type F pavers are a minimum of 2-5/8" thick and are used when the design calls for a proper base with a sand setting bed. The 2-5/8" thickness meets the 3 to 1 aspect ratio (thickness to length on a 4" x 8" paver) necessary to achieve paver interlock under heavy loading. For a typical residential driveway or a light/medium traffic commercial job, the added cost of a heavy vehicular design is not necessary and pavers meeting ASTM C 1272 would not be required. In those applications, pavers meeting ASTM C 902 would apply. Critical to the performance of the pavers after base considerations is the type of bedding sand, joint width size, pattern chosen, joint sand retention, edge restraint and drainage. Bedding Sand: We recommend that the bedding sand conform to ASTM C33 and that the specification exclude all stone screenings that may pass the C33 sieve analysis. Stone screenings tend to break down over time causing joint sand loss and may contain soluble salts causing efflorescence. Concrete sand is best. Joint Width: Research from Lilley and Clifford indicate that a 3mm joint size is optimum for generating the strongest interlock between the individual units. Our English Edge paver features spacer nibs to aid the installer in creating optimal and consistent joint widths for good interlock. Pattern: For vehicular traffic, the herringbone pattern is universally recommended as the nature of this pattern dissipates traffic load more effectively than any other pattern. Joint Sand Retention: Joint sand loss is the most common cause for vehicular pavement failures. The causes for sand loss can be among the following: excessive run off, tire suction, poor drainage, inadequate bedding or joint sand, poor base design, street cleaning. Joint sand stabilizers and cement & sand mixtures have been used to prevent sand loss over the years and have proved effective given sound system design. The drawbacks to cement & sand mixtures are that the mixture tends to break down over time due to traffic loading and the pavers will need cleaning after installation. Stabilizers may leave a sheen to the pavers under certain lighting conditions and will have to be reapplied after 3 to 5 years depending on joint condition. Edge restraint: An adequate edge restraint is important to the proper functioning of any segmental paving system, vehicular or pedestrian. A DOT approved curb system will work fine as an edge restraint in street applications. For crosswalks, the general industry recommendation is to use concrete banding to prevent any displacement of the edge restraint under traffic loading. Drainage: After the joint sand has fully compacted creating a full joint of sand, 90% of surface water will run off over the surface of the pavers. We recommend a 2% grade to ensure this run off. In rigid base pavement, we recommend weepholes in the concrete to allow water draining through the pavers to escape. The weephole should be covered with a filer fabric so that sand will not clog the weephole. GENERAL MAINTENANCE & CLEANINGPine Hall Pavers require no special maintenance as natural weathering keeps most clay paving systems clean and beautiful. For specific cleaning situations such as oil stains or moss removal, there are commercial cleaners available such as StandOff® cleaners for paving products. As a general rule when using these types of cleaners, always test on a small hidden portion of the pavement; Prewet pavement thoroughly before cleaning and rinse after with clean water; In mortared applications, pressure washers can be used provided application pressure is limited to 30-50 psi and a 50 degree fan tip is used. Rinse pressures should not exceed 200-300 psi. In all cases, DO NOT USE MURIATIC ACID. For English Edge Rose FR/Rose LR/Buff, Rosewood, Cocoa or Carytown, use VanaTrol (or equivalent) for mortar cleaning or a detergent cleaner for general cleaning. For moss removal, a one to one mixture of water and bleach is generally effective. When using any cleaning solution make sure to follow the label guidelines for application and safety. In flexible based applications, pressure washers are not recommended as the pressure washer tends to remove joint sand that compromises interlock. We suggest using a stiff application brush and a normal pressured garden hose. Loss of jointing sand may occur over time due to natural exposure. Check annually for sand loss and re-apply jointing sand as necessary. Snow and ice can be removed with normal hand equipment or motorized vehicles. Snowplow blades should be equipped with a rubber edge and set @ 1/4" above the pavement. Rotary brushes and snow blowers can also be used. The use of rock salts is not recommended for snow and ice removal because of the possibility of efflorescence. Non-sodium de-icers that are environmentally compatible are available as well as sand or cinders for traction control. EFFLORESCENCEEfflorescence is a crystalline salt deposit on the surface and in the pores of concrete, masonry, and other building products. A phenomenon reported as early as the 1870's and much studied since, it can appear as sulphate and carbonate compounds of sodium, potassium, calcium, ma gnesium and aluminum. Chlorides may also occur as efflorescence. There are several sources for efflorescence: 1) the movement of groundwater that moves upwards, by capillary action or "wicking", into masonry or concrete materials. 2) salts in the soil that are in contact with paving can migrate above grade. 3) natural-state salts that are found in mortar, concrete or other building products. 4) contamination of masonry components (including sand) by seawater. 5) the improper use of hydrochloric acids in cleaning solutions. 6) the use of calcium chloride as a mortar accelerator. 7) the use of lime base aggregates as a base material or as bedding sand in the form of screenings. 8) salts used for de-icing purposes in the winter months, the most common outside source of efflorescence in paving applications. Although rare, some raw material used to make clay brick contains small amounts of salt. However, these small amounts are minor compared to studies that found two to seven times as much soluble material in concrete products versus fired clay material. W.E. Brownell concluded in his research study that the most common form of efflorescence comes from the "migration of 'free-alkali' solutions from cementatious products." This would include any newly poured concrete curb, foundation or sub-base slab. Efflorescing salts dissolve in water and are absorbed into the masonry pores. Typically, clay bricks can absorb 5% to 8% of their weight in water. Heat from the sun (or other source) begins to draw the moisture to the pavement surface and as the water completely evaporates, the salt deposits are left on the surface. Since humidity and moisture play a key role in the efflorescence process, some areas of the country will be affected more than others. Seasons will play a role as precipitation during season changes will increase the likelihood of efflorescence. The most important solution to solving efflorescence is the avoidance of efflorescing materials in the paving system. The second best solution is finding, locating and dealing with the source of water. Since the source of water in a paving application is generally clear, the most important factor in limiting the occurrence of efflorescence is insuring adequate drainage of the pavement through grading or specific drainage systems. Good drainage will keep the pavers dryer and thus, they will be less likely to effloresce. While efflorescence control systems are available, they don't guarantee full arrest of the problem and tend to be expensive. The best thing to do is to allow the efflorescence to run its course provided that the paved area has good drainage. The main reasons for these recommendations are as follows: the source of the salt is most likely coming from base materials, mortar or de-icing salt residue. In a flexible base application, after 6 months, 90 % of the water will run off the paving surface and away from the pavers versus down through the joints. This change should carry the salts in solution into the ground rather than into the pavers. In all cases, free salts dissipate eventually and the problem goes away for good, generally within 18 months. As a general rule, the removal of efflorescing salts from the face of masonry is a relatively easy operation. Efflorescing salts can be removed with dry brushing or with clear water and a stiff brush. For further reference, see BIA Technical Notes- 23, 23A, 20. StandOff® & VanaTrol cleaners are manufactured by ProSoCo, Inc., Kansas City, KS. Other cleaners from different manufacturers are also available. DIAMOND BLADE RECOMMENDATION- Not all diamond blades are equal. There are different diamond blades made to cut green concrete, brick, block, refractory, etc.... Hard, dense materials like PHB Pavers need a softer bond matrix with a higher diamond concentration to cut effectively. - Using a diamond blade in the wrong application can be expensive. A concrete blade with a hard bond matrix cutting PHB pavers will glaze over or polish after a few cuts and will quit cutting but still show segment life. - For best performance, optimum Surface Feet per Minute cut rate is 10,000 to 12,000. Harder materials like brick cut better at lower RPM's. Determine the best RPM speed through surface feet per minute calculations. The formula to calculate SFM is [blade diameter x 3.14 x RPM]/12"= SFM - Generally, the more horsepower (torque) applied to the blade shaft, the more efficient the cutting action. Remember, lower horsepower may require softer bonds or less diamonds to cut efficiently. - Improper RPM's can cause blade wobble and may create dangerous cutting conditions causing injury. - Excessive pressure can dull the blade and cause it to cut slower or not at all. Let the diamonds do the work. - High speed saws should use a blade specifically designed for high RPMs and not exceed 16,000 SFM.
