The most important B asphalt concrete pavement repair should be 100 ~ 200m test section, the main points the trial mix, test at two stages, to obtain the corresponding parameters. The end of C hot mix asphalt pavement construction after natural cooling, the surface temperature is lower than 600C, can allow the vehicles to pass. D hot mix asphalt layer and the adjacent two spoke horizontal construction joints should be staggered over 1m. Answer: C Analysis: when the mixture of high temperature of the surface of the opening, easy to form a rut. 2, the city main road, on the road, in the surface layer of asphalt mixture through the test (test, rutting resistance, dynamic stability index is A Marshall. Answer: B analysis:. Temperature stability test mixture under high temperature in the summer season, should do the rutting test. 3. city trunk road, expressway construction temperature of hot mix asphalt (below, not construction. Answer: D B.18 A.15 C 12 D.10) 0 C B. C. D high temperature rutting compressive strength bending) Analysis: the construction of asphalt pavement at low temperature, prone to compaction of asphalt pavement early enough, cracking, etc. over 4. diseases. The quality of hot mix asphalt mixture paving the echelon form during the operation of longitudinal joints should be used. The upper and lower heat joints should be staggered longitudinal seam (above A.50mm). Answer: B the upper and lower longitudinal joints staggered, mainly to avoid reflection cracks. The 5. city expressway, trunk road asphalt concrete mixture should be used (A continuous mixing.
