بیشترRecycled Asphalt As more of our asphalt pavements wear out, many of them are recycled. This is usually done by milling or crushing. Sometimes the material is available for use on a gravel road. It can be a good surface, but there are pitfalls. In this material, the bituminous portion of the old pavement becomes the binder.

However, any load or loads of mixture which, in the opinion of the Engineer, are unacceptable for reasons of excessive segregation, aggregates improperly coated, or of excessively high or low temperature will be ...
بیشترHow is the Florida Texture Meter changing the way we can detect asphalt pavement segregation? Florida Texture Meter (FTM) is a tool developed by FDOT to quantify asphalt texture and detect segregation. FTM is a portable laser-based device that measures the surface texture of pavement in terms of mean profile depth.
بیشترSegregation: causes and cures. Segregation in a hot mix asphalt (HMA) mixture can be defined as the separation of the coarse aggregate particles in the mix from the rest of the mass. The segregation can take one of three forms—random, side-to-side or longitudinal, and truckload to truckload. Each type of segregation is caused by a different ...

بیشترThe visual inspection method is considered a basic and widely used method to detect segregation. Also, pavement surface texture measurement has frequently been used to determine segregation. The Florida Department of Transportation (FDOT) has recently developed the Florida Texture Meter (FTM) to measure pavement texture.

بیشترFatigue cracking is an important concern when a high percentage of Reclaimed Asphalt Pavement (RAP) is used in an asphalt mixture. The aging of the asphalt binder reduces its ductility and makes the pavement more susceptible to cracking. Rejuvenators are often added to high-RAP mixtures to enhance their performance. The aging of a rejuvenated binder is different from asphalt.

بیشترAsphalt mixtures should never be heated over 350 deg F. Non-modified mixtures are typically heated closer to 300 deg ... Observe proper loading procedures to minimize segregation. The best way to load the truck is front or back first, the other end second, and the middle third. The HMA should be dropped in small batches into the truck.
بیشترFor acceptance, the gradation, asphalt content and VMA must be within the limits outlined in Table 2 . The mat density must be greater than or equal to 94.5%, the air voids must be 3.5% ± 1% and the joint density must be greater than or equal to 92.5%. Unlike requirements on Florida DOT jobs, FAA jobs require coring on the longitudinal joints.

بیشتر"Segregation" is a term often used in the HMA industry to describe a number of different phenomena. It's most general definition comes from Stroup-Gardiner and Brown (2000 [1]): "Segregation is a lack of homogeneity in the hot mix asphalt constituents of the in-place mat of such a magnitude that there is a reasonable expectation of accelerated pavement distress(es)."

Superpave mixes are identified as Type SP-9.5, Type SP-12.5 or Type SP-19.0. Obtain Superpave Asphalt Concrete from a plant that is currently on the Department's Production Facility Listing.
بیشترWhen segregation is present in a mixture, there is a concentration of coarse mixture in some areas, while other areas contain a concentration of finer aggregate. The segregation may cause rutting issue of asphalt pavement but there is no agreement based on literature review. Prediction [1].
