Abstract

The invention discloses a detection method for stabilizing broken stone gradation by cement. According to the invention, a mass m0 of a broken stone sample stabilized by cement is measured in the step1-step 7, the mass m1 and the mass m2 of the broken stone sample stabilized by cement after drying are respectively measured, the mass m3 of the dried particles having a particle size being greater than or equal to 0.075 mm in an aggregate can be measured, and the grader retained mass mi of the aggregate at a filter sieve with a diameter of the sieve aperture being I is measured; according to theabove m0, m1, m2, m3 and the cement dosage omega, the water content Rho of the broken stone stabilized by cement, the mass of the cement and aggregate and ma, the aggregate mass mb and the aggregategradation parameter can be calculated, the gradation detection of the broken stone stabilized by cement is realized, full dissolving of the cement in the broken stone stabilized by cement can be guaranteed through the step 5), a mixture m3 the sieve does not contain the cement, the gradation detection accuracy is increased, and gradation parameter of the broken stone stabilized by cement on on-site construction can be accurately reflected, so that the broken stone stabilized by cement is subjected to mass monitoring from the construction process and result.

Description

technical field [0001] The invention relates to the field of material testing and analysis, in particular to a method for detecting the gradation of cement-stabilized gravel. Background technique [0002] In recent years, the scale of my country's highway construction has continued to expand. With the rapid growth of road traffic, especially the rapid growth of heavy vehicle traffic, high requirements have been put forward for the carrying capacity and use intensity of roads. At present, the pavement structure of my country's highways mainly adopts the semi-rigid base asphalt pavement structure, which is made of various aggregates and soils stabilized by hydraulic materials (also known as inorganic binders) as the semi-rigid base, and paved on the semi-rigid base. A certain thickness of asphalt mixture surface layer is formed. [0003] Cement-stabilized crushed stone is a roadbed material formed by adding a small amount of cement and water to graded crushed stone, which is u...
