Relying on Gansu Hengshi Highway Detection Technology Co., Ltd.[url=http://chipspreadermarket.com/road/3198.html]vibratory compactor for sale[/url] Gansu Province Highway Network Monitoring Key Laboratory recently completed the "special climate in Gansu Province asphalt pavement cracks at room temperature sealant application technology research" research work.
In the first part of the study, the causes of highway cracks and their main measures were investigated by means of issuing questionnaires and field reconnaissance. Secondly, the actual situation of different brands and different types of sealant products in the province were compared,[url=http://chipspreadermarket.com/road/3158.html]road paving steel drum rollers[/url] And draw on the domestic and international industry standards for the performance test, a comprehensive evaluation of the performance of the existing sealant, and finally through the close combination of production and research, independent research and development of sealant products and the preparation of sealant construction local standards. This paper puts forward the classification and corresponding evaluation methods of asphalt pavement sealant, and recommends the technical requirements and the conditions of use of the asphalt pavement sealant in the representative area of Gansu Province. According to the research results,[url=http://chipspreadermarket.com/road/4816.html]advanced asphalt pavement repair vehicles[/url] the asphalt Road surface sealant construction machinery, construction technology, construction quality control standards and engineering acceptance criteria. At the same time, "Gansu highway asphalt pavement heating sealant construction technical regulations" local standard project, independent research and development of sealant products to achieve results into the smooth production. |
