腾瑞线公路设计计算书+图纸(3)

Pavement design includes asphalt pavement design and concrete pavement design, first converted to standard axle load and cumulative equivalent axle times, and then proposed the thickness of each layer of material。 (3 cm thick), the middle layer with medium-graded graded asphalt concrete (thickness 5cm), the use of three-layer asphalt concrete layer, the surface layer with fine graded graded asphalt concrete (thickness 4 cm) The lower layer of coarse graded graded asphalt concrete (thickness 6 cm)。 The compressive modulus and splitting strength, soil elastic modulus, design deflection value, and allowable layer bottom tensile stress of each layer are determined。 The thickness of ordinary concrete is 0。25m。 Base selection of lime-fly ash, thick 0。20m, E1 = 600Mpa。 The cushion is lime soil, 0。20m thick, E2 = 500Mpa, the plate size is 4。5m wide and 5。0m long。 The longitudinal seam is the flat seam and the transverse joint is the slit (false seam)。 Seam processing, horizontal joints, longitudinal joints, swell joints, shrink joints, transverse joints and construction joints of the treatment, but also in the edge, corner reinforcement, configuration, place reinforcement reinforcement。 Concrete pavement with the flexible road junction, in order to avoid the occurrence of subsidence and wrong, or flexible pavement by the push and should be set up to meet the road junction。
