An evaluation method for energy saving and emission reduction during the construction period of asphalt roads

Abstract

The invention discloses an evaluation method for energy saving and emission reduction during the construction period of asphalt roads. The method comprises: establishing an evaluation index for the construction period of asphalt roads, obtaining the actual conditions during the construction period of asphalt roads through actual measurement or on-site survey, and combining the proposed Determine the evaluation index limit or evaluation standard of the asphalt road construction period, and determine the evaluation value of each index during the construction period of the asphalt road. Combined with the weight of each evaluation index, determine the overall energy saving and emission reduction evaluation value, which is the quantification of the energy saving and emission reduction level during the asphalt road construction period. On the one hand, the method of the present invention comprehensively considers factors such as material application, machine use, and process organization in the asphalt road construction process, and can better evaluate the pollutants and energy consumption levels in the asphalt road construction; on the other hand, the technology is based on a large number of construction Based on the environmental test data and energy data, a quantitative and qualitative evaluation index is proposed, which can accurately distinguish and evaluate the energy-saving and emission-reduction levels of different road constructions.

Description

technical field [0001] The invention relates to the fields of asphalt road construction and energy saving and emission reduction, in particular to an evaluation method for energy saving and emission reduction during the asphalt road construction period. Background technique [0002] The Ministry of Transport implemented the "Technical Requirements for Evaluation of Green Transportation Facilities Part 1: Green Highway" (JT / T 1199.1-2018) on August 1, 2018. This standard aims at the green level of highways from design, construction and operation stages An evaluation index system is proposed. The evaluation index system puts forward index requirements for highway construction from seven aspects: green concept, ecological protection, resource conservation, energy saving and low carbon, safety and wisdom, quality construction and warm service. [0003] The target of this indicator system is the whole construction cycle of national highways from design, construction, operation, ...

AI Technical Summary

Problems solved by technology

[0003] The target of this indicator system is the whole construction cycle of national highways from design, construction, operation, etc., and it covers a wide area. In-depth and accurate evaluation and analysis

In addition, the evaluation index system does not propose more accurate evaluation indexes and limit requirements in terms of environmental air protection, which is not conducive to the evaluation of ambient air in the process of road construction.

[0004] This evaluation index system has a high application value for the overall construction evaluation of the highway, but it lacks practicability and operability for the evaluation of the construction links in the entire construction cycle of the highway, which is not conducive to technicians using this technology to construct a certain highway. Evaluation of the level of energy saving and emission reduction in the long term
