Pavement structure at old medial strip position after unilateral widening of expressway
The invention discloses a pavement structure at the position of an old medial strip after unilateral widening of an expressway, and relates to the technical field of road engineering. The pavement structure sequentially comprises a dense water type asphalt mortar layer, a drainage anti-crack large-gap asphalt mixture layer, a reinforced concrete layer, a high-toughness polyester fiber bundle grating, a micro-permeation asphalt mixture lower surface layer, a high-modulus asphalt mixture middle surface layer and a high-skid-resistance asphalt mixture surface layer from an old roadbed to the top. Wherein the top face of the reinforced concrete layer is provided with a longitudinal drainage gravel blind ditch, a vertical PVC drainage pipe penetrating through the reinforced concrete layer is arranged in the blind ditch, a transverse drainage pipe is arranged on the bottom face of the drainage anti-crack large-gap asphalt mixture layer, and the vertical PVC drainage pipe downwards penetrates through the drainage anti-crack large-gap asphalt mixture layer and is communicated with the transverse drainage pipe. The anti-rutting performance and the drainage performance of the old medial strip after the old medial strip is paved into the heavy-load lane of the expressway can be effectively improved.
本发明公开一种高速公路单侧加宽后旧中央分隔带位置的路面结构，涉及道路工程技术领域，路面结构平齐于高速公路道路表面，路面结构从旧路基向上依次包括密水型沥青胶砂层、排水抗裂大空隙沥青混合料层、钢筋混凝土层、高韧性聚酯纤维束格栅、微渗透沥青混合料下面层、高模量沥青混合料中面层和高抗滑沥青混合料表面层；其中，钢筋混凝土层层顶面设置纵向排水碎石盲沟，盲沟中设置贯穿钢筋混凝土层的竖向PVC排水管，排水抗裂大空隙沥青混合料层底面设置横向排水管，竖向PVC排水管向下贯穿排水抗裂大空隙沥青混合料层并连通横向排水管。本发明可以有效提升旧中央分隔带位置铺装为高速公路重载车道后的抗车辙性能和排水性能。
