Each plate material mixing temperature difference of less than 5 ℃, mixing time difference is less than 3s. 2 ,. colored hot mix asphalt concrete mixing methods and technical requirements with ordinary asphalt concrete is basically the same. 3, prior to production color asphalt concrete, mixing tanks should be cleaned, binders transfer line should be provided separately to prevent contamination of the original black asphalt. 4, for the pigment distribution, mixing time should be reasonably determined. Mixing time is generally better than ordinary asphalt concrete increase 10 ~ 15s 5, the construction temperature should be colored asphalt binder viscosity was measured at 135 ℃ and 175 ℃ condition by - temperature curve is determined. In the absence of viscosity-temperature curve data, reference may be selected from the following: color asphalt binder heating temperature 155 ~ 165 ℃, stone heating temperature of 165 ~ 175 ℃, the material temperature 145 ~ 165 ℃.

(Nanchang asphalt | Jiangxi asphalt | Asphalt Pavement Nanchang | Jiangxi colored asphalt | Jiangxi spraying emulsified asphalt | Jiangxi asphalt works | asphalt pavement construction in Jiangxi | Jiangxi asphalt concrete mixing stations), factory mixing plant was established in 2009 In Pingxiang road asphalt, it is a professional road asphalt industry chain integrated company, providing customers with a full range of asphalt industry services, business areas mainly for asphalt pavement construction, spraying emulsified asphalt, marketing and processing, asphalt pavement construction The equipment leasing business asphalt asphalt concrete pavement classification used by combining different materials can be divided into two categories of petroleum and coal tar pitch; some countries are also using or mixing of asphalt mixed with natural. Aggregates used by different varieties, road asphalt supply, can be divided into gravel, gravel, sandy, several types of slag to gravel using the most common. Different maximum particle size of the mixture, can be divided into coarse (35 to 40 mm), medium-grained (20 to 25 mm), fine particles (10 to 15 mm), sand (5-7 mm), etc. the number of classes. Press the compactness of the mix can be divided into dense graded, semi open-graded and open-graded and several categories, open-graded asphalt mixes, also known as gravel. Wherein the thermal spread of dense hot mix Macadam durable, high strength, good integrity, is the construction of the High Representative of asphalt pavement materials, the most widely used application. States have different asphalt concrete formulation of norms, China has formulated hot mix asphalt hot shop technical specifications to the porosity of 10% or less are known as asphalt concrete, subdivided into Ⅰ and type Ⅱ, Ⅰ type of porosity and was 3 (or 2) to 6%, is a dense-graded type; Ⅱ type is 6 to 10%, is a semi-open-graded type; porosity of 10% or more are known as bitumen macadam, is open-graded type; mixed physical and mechanical properties of materials have stability, and porosity of the current value. Nanchang Road highway Engineering Co., Ltd. (Nanchang asphalt | Jiangxi asphalt | Asphalt Pavement Nanchang | Jiangxi colored asphalt | Jiangxi spraying emulsified asphalt | Jiangxi asphalt works | asphalt pavement construction in Jiangxi | Jiangxi asphalt concrete mixing stations), factory mixing plant was established in 2009 , is a professional road asphalt industry chain of integrated companies, provide customers with full service asphalt industry, petroleum asphalt road, the main business areas of asphalt pavement construction, spraying emulsified asphalt, marketing and processing, asphalt pavement construction equipment leasing business. strength of asphalt concrete pavement asphalt batching mainly in two ways. First, asphalt cement and slag forming material adhesion; the other is a set of locks in the frictional resistance and knot strength material particles. Slag fine particles (mostly less than 0.074 mm) of the large surface area of ??asphalt material to form a film, thereby increasing the bonding strength and temperature stability of bituminous material; and the lock junction force is mainly generated between the coarse aggregate particles. Select asphalt concrete aggregate gradation to take into account both when equipped to meet after adding an appropriate amount of asphalt mixture can form a dense, stable, roughness suitable, durable pavement. There are many ways with the mineral aggregate, can be calculated to be empirically prescribed gradation range, China's current range of experience using the grading curve. Asphalt appropriate amount of asphalt mixture, asphalt road 100 #, should the results of laboratory tests and practical situations to determine which site is generally in the relevant specifications are listed there may refer to the amount of pitch range assigned as a guide for the test. When the mineral aggregate varieties, grading range and type of asphalt consistency, mixing facilities, climate and traffic characteristics than the fixed, can also be used to estimate the empirical formula. 70 # road asphalt | asphalt road construction in Nanchang Quote | Pingxiang Road Asphalt Co., Ltd. provided by Nanchang Road through asphalt road projects.
