Disclosed are asphalt binder compositions and methods for making such compositions with pure sterol:crude sterol blends. The sterol blends improve various rheological properties.

Particulate infill from a worn down infilled artificial turf, particularly a sand/rubber mixture which includes crumb rubber from vehicle tires, is extracted from a prior field and then thereafter incorporated into the top surface of the compacted base at the same site, thereby to assure better drainage conditions in the compacted base for the subsequently installed field. The extracted and incorporated infill helps to maintain open drainage channels throughout the top of the compacted base, particularly in areas where limestone is prevalent. Otherwise, the limestone fines are susceptible to compacting and creating a cement-like crust at the top of the base. An existing infill extractor/collector device is modified to operate in a second mode, so that instead of merely performing the conventional bagging of the already-used infill, the already-used infill is laterally diverted back on to the base at the same site, and thereafter, distributed and tilled into the base. By incorporating the extracted infill into the base of the new field, the need to bag, remove, and dispose of the used infill is eliminated, along with the time and costs associated therewith, while at the same time improving the drainage of the new field. Two structures for diverting the collected infill are disclosed.

The invention relates to a planning system and method for operating one or more road milling machines. In that context, material properties of a road are captured and are geographically associated with one or more roads or road segments. Based on the material properties, an expected milling output of a road milling machine is ascertained, in the context of carrying out milling tasks on the road, or an expected wear on the milling tools. An optimized sequence of milling tasks to be carried out is created on the basis of those data. Accordingly, the invention may enable optimized deployment of the one or more road milling machines and of resources necessary for carrying out the road milling tasks. Aspects of the planning system may be remotely implemented for centralized application with respect to each of the road milling machines, or locally implemented for individual road milling machines.

A fatigue-resistant flexible road structure that includes one or more sub-base structural support layers positioned over a compacted earth foundation. At least one of the sub-base structural support layers is an elastic sub-base layer for more completely distributing surface loads. The elastic sub-base layer includes aggregate, filler, binder, and recycled tire rubber. The recycled tire rubber is included in an amount of 3% to 5% by weight of the sum of aggregate, filler, and rubber. The elastic sub-base layer has a fatigue life at least 25 percent greater than a non-elastic sub-base layer without recycled rubber. Further, the elastic sub-base layer has a modulus of elasticity at least 25 percent lower than a non-elastic sub-base layer without recycled rubber.
