摘要

本文将介绍高温对沥青街道路面的影响,即温度对永久变形的影响,从而对街道的技术状况产生影响,并与对城市外道路的影响进行比较。环境因素是运营中受到冲击的主要因素之一,道路结构对国家道路运输技术基础设施的影响非常重要。将介绍城市道路结构(街道)与城市外道路(道路)在施工、交通需求和所受环境条件方面的差异。城市外围与城市区域的道路结构在区位环境条件不同的情况下要求不同,即当街道位于区位内且建筑环境对道路基础设施影响较大时,与道路位于住区外的情况不同,减少气流积聚路面表面温度的影响。为了证明高温对路面的影响,对沥青混合物进行了实验室测试,以证明物理特性降低的发生,对类似交通的应用性能产生不利影响。

Influence of high temperatures on technical state of streets and roads structures with asphalt surfacing
Abstract In this paper will be presented the influence of high temperatures on asphalt street pavement in terms of the influence of temperature on permanent deformations and thus the technical condition of the streets, comparable to the effects induced on extra-urban roads. Environmental factors are one of the mayn factors being assaulted in operation and road structures are very important in terms of the influence they can have on the state road transport technical infrastructure. Will be presented differences between urban road structures (streets) and extra-urban (road) both in terms of construction, the demands of traffic and environmental conditions to which they are subject. Road structures extra-urban and urban areas are required differently in terms of the environmental conditions of the location ambient different thereof, that is, when the streets they are inside localities and the built environment significantly affect road infrastructure, unlike in the case of roads where they are located just outside the settlements, reducing the effect of air currents accumulation pavement surface temperature. To demonstrate the influence of high temperatures on the pavement were conducted laboratory tests on asphalt mixtures in order to demonstrate the occurrence of reduction of physical characteristics, with adverse implications on the performance of applications similar to traffic.
