Novel road and construction method thereof

Abstract

The invention relates to a novel road which comprises a cement-stabilized soil layer, a graded broken stone hardcore, a cement-stabilized graded broken stone subbase layer, a roller compacted concrete base layer, an asphalt mastic broken stone structural layer and an asphalt thin overlay which are sequentially paved, according to the the cement-stabilized soil layer, gravel soil or sandy soil is selected as filler, the maximum nominal particle size of the filler is smaller than or equal to 53 mm, the soil particle non-uniformity coefficient is larger than 10, the liquid limit is smaller than or equal to 40, the plasticity index is smaller than or equal to 12, and the organic matter content is smaller than 2%. The asphalt mastic macadam structure layer can effectively relieve the time that reflection cracks penetrate through the pavement, so that the durability of the pavement is improved, the service life of the pavement is prolonged, meanwhile, the total thickness of the pavement structure layer can be reduced, geological materials are saved, and the construction period of a project is shortened. The invention further relates to a construction method of the novel road.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a novel road and a construction method thereof. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] During the road operation process, due to the long-term high-load operation of the pavement structure and the settlement of the roadbed, different damages will occur on the road surface, such as the reflective cracks of the roadbed penetrating the road surface, cracking potholes and other diseases caused by roadbed settlement, which have serious consequences for driving safety. There are certain hidden dangers, and later...
