摘要:
针对微表处混合料的抗裂、抗变形不足等问题,采用加纤技术并运用纤维分散试验、纤维微表处混合料拌合试验、路用性能试验及低温抗裂试验对其性能进行研究。结果表明:采用自主研制的专用设备进行纤维分散,可保证加纤微表处混合料中纤维的均匀分布; 纤维微表处混合料中纤维的适宜长度为6 mm; 纤维添加量为0.2%时,加纤微表处混合料1 h及6 d时的湿轮磨耗值最小; 纤维添加量为0.1%时,混合料黏附砂量最小,但和纤维添加量为0.2%时混合料粘附砂量差别不大; 纤维添加量为0.3%时,加纤微表处混合料低温劈裂强度最大。综合各指标结果,确定纤维添加量为0.2%时,纤维微表处混合料总体路用性能最佳。
Abstract:
Aimed at problems of insufficient resistance to cracking and deformation of micro-surfacing mixtures,a fibre reinforced micro-surfacing technique was put forward and its performances were studied.The fibre dispersion,the mixing time,the road performance, and the low-temperature resistance to cracking tests of fibre reinforced micro-surfacing mixtures were carried out.The results indicated that the fibres in fibre reinforced micro-surfacing mixtures could be homogeneously dispersed using the self-developed special equipment.The suitable length of fibres in fibre reinforced micro-surfacing mixtures was 6 mm.When the added volume of fibres was 0.2%,1 h and 6 d wet track abrasion values were the minimums.When the added volume of fibres was 0.1%,the volume of load wheel test(LWT)sand adhesion was the smallest,and as the added volume of fibres was 0.2%,the fibre reinforced micro-surfacing mixture showed better performances and moreover,there was not much difference in the sand adhesion between these two added volumes of fibres.When the added volume of fibres was 0.3%,the low-temperature splitting strength was the greatest.According to the test results of various indexes 0.2% was selected as the optimum added volume of fibres thus it could obtain the better comprehensive performances.
