As the use of non-woven geotextile cracked asphalt surface on the basis of the stress absorption delaying reflective cracking thin layer is effective measures, but the needle-punched nonwoven geotextiles performance will directly affect the effect of delaying reflective cracking. Needle-punched nonwoven geotextiles for road pavement delaying reflective cracking should have the following project characteristics: 1, good temperature resistance. Temperature asphalt hot shop when more than 150 degrees, higher asphalt temperature, requiring needle-punched nonwoven geotextile material at a temperature of not only this construction does not melt or soften, and can maintain normal operation. It requires a temperature of 170 degrees capability 2, tensile strength and mass per unit area and other indicators should meet the technical requirements (tensile strength kn / m> 8, mass per unit area g / m) 3. Good asphalt adsorption. General construction is to uniformly sprayed layers of asphalt, holes and needle-punched nonwoven geotextiles, non-woven geotextile should be able to absorb the asphalt and saturated, requiring non-woven geotextile has good adsorption capacity. 4. Good flexibility. Flexible include toughness and surface hardness double meanings. . Ability toughness reaction nonwoven geotextile to absorb impact energy of Tongling Special woven geotextile, which can be approximated to the product tensile strength and elongation of the material measure; generally cbr experiment bursting strength to represent its surface hardness. 5. Good uniformity. Acupuncture non-woven geotextile anisotropic material, in order to ensure uniform strength, bidirectional intensity ratio should not exceed 1.2. In general, without the use of non-woven geotextile woven geotextile. 6, acid 7 anti-aging properties. Requirements needle-punched nonwoven geotextiles in roads to maintain a normal working condition over its useful life. 8, thickness requirements. To prevent needle-punched nonwoven geotextile plus set adverse negative effects asphalt surface Tongling Special woven geotextile, nonwoven geotextile acupuncture response thickness strictly limited, should generally be less than 2.0mm. Geotextiles pavement cracks in the actual work the promotion of pavement crack use is a great danger of pavement disease. Causes of geotextile their produce into two categories, namely, non-load load cracks and cracks. Fatigue crack load caused mainly by traffic loads generated by the destruction of non-load crack usually temperature and humidity changes, and the characteristics of the material itself caused, there are some cracks are caused due to the differential settlement of subgrade. This is mainly semi-rigid base is formed by compaction under optimum moisture condition, the stress change with the passage of time and external conditions, when the material itself can not resist tensile stress changes caused by the outside world, it will cracking phenomenon. This crack is wet crack Tongling Special woven geotextile, these cracks are generally produced at an early stage can lead to surface reflection cracks; and because semi-rigid structure is almost completely impermeable layer, seepage from the road surface, accumulate in the grass surface can not be excluded. With the rapid development of economic construction, road construction in the ascendant in recent years across the country to build a large number of highway and city Expressway, where the semi-rigid pavement has been more widely used. Semi-rigid pavement base is an inorganic binder as the bearing layer of the pavement structure, compared with a pellet-like material as a flexible pavement pavement layer, with high strength, high capacity, good integrity, rigidity advantages. But it also has its own shortcomings, its resistance to temperature, moisture resistance to deformation is poor, easy to form a wet shrinkage cracks and shrinkage cracks, and thus make the road reflective cracks Tongling Special woven geotextile, leading to cracking of the asphalt surface, the impact of road use quality, shorten pavement life. Disease lot of semi-rigid pavement structure, reflecting reflective pavement cracks, pavement damage is more important reason, thus reducing pavement reflection cracking is particularly important.
