9、changes for this guide specification are welcome and should be submitted as a Criteria Change Request (CCR).*NOTE: To achieve reinforcement by the use of fabrics in asphalt pavement, their range of application must not be overextended. Fabrics have been used successfully in many applications but, li

10、kewise, have failed to improve pavement performance in similar situations. Experience has shown, although long-term performance data is not available, some fabric enhance the life of thin asphaltic resurfacings. When used with asphalt overlays of 75 mm 3 inches or less, reduced reflection cracking c

11、an be achieved. The fabric not only retards or reduces reflection cracking but prevents surface infiltration of water. Fabrics have performed well when used on pavements with fatigue cracking (alligator skin pattern), on longitudinal construction joint cracks in asphalt pavement, and on the longitud

12、inal joint between portland cement concrete pavement widened with SECTION 32 01 17.62 Page 3Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-flexible pavement. In general, fabrics have not proven to serve as well on cracks that are greater than 6 mm 1

13、/4 inch wide. In these cases, the fabrics have not prevented a significant amount of reflection cracking but are believed to protect the pavement from surface water intrusion.*PART 1 GENERAL1.1 REFERENCES*NOTE: This paragraph is used to list the publications cited in the text of the guide specificat

When selecting an asphalt cement material and the temperature is known, the fabric manufacturers requirements should be consulted. Give consider

38、ation to the following items in the selection of asphalt cement: Major criteria include climatic conditions, traffic density, wheel loads, and local availability. In general, AR-8000 or AC-20 or 60-70 is used in hot climate areas and in projects where heavy traffic density or high wheel loads occur.

39、 AR-4000 is used in most temperate regions for projects with average traffic density. AR-4000 or AC-10 or 85-100 could be used in cold climate areas for projects with heavy traffic density.
