The paper is based on the construction of the express - highway between yiyang and changde in hunan province, aiming at enhancing the serviceability of cement concrete pavement, probing into the structural assemblage of the cement concrete pavement, the roadway drainage system, contraction joint with the dowel bar and precaution of bumping at the end of the abutment. it presents some achievements of the research, including more reasonable structural assemblage and roadway drainage system, the method of setting dowelled bar in contraction joint, putting forward the concept of stage - transition from rigid to flexile behind abutment
本文以湖南省益陽至常德高速公路項目為依託，以提高水泥混凝土路面使用性能為目標，就水泥混凝土路面結構組合、路面排水系統、縮縫設置傳力桿、橋頭跳車問題的防治等方面開展研究和工程實踐，取得了豐富的研究成果，如研究採用了更合理的路面結構組合，設置了較完善的路面排水系統，在國內高速公路上率先全面採用縮縫加傳力桿技術，對所有橋涵構造物臺背全部採用剛柔過渡技術處理橋頭跳車問題等。 -
This paper used the reactive powder concrete ( rpc ) as the inorganic anchoring material, and studied this material ’ s compositions and the materials mechanics properties ( mainly includes compressive strength, shearing strength, elasticity coefficient and poisson ' s ratio ), and also studied the contraction, durability ( including the rpc permeability, chemistry corrosiveness and anti - frozen performance ) and the heat - resistance of rpc
本文採用活性粉末混凝土（ rpc ）為無機錨固材料，並對該材料的配合比，材料力學性能（主要包括抗壓強度，抗剪強度，彈性模量和泊松比）進行研究，還分析了rpc的收縮性、耐久性能（包括rpc的滲透性、化學侵蝕性和抗凍性能）和耐高溫性能。
