Soil form system supporting hardscape thereover

Soil form structure for supporting hardscape and corresponding vehicle, pedestrian traffic, and other loads while maintaining uncompacted or loosely compacted soil underneath. A number of cell structures may be coupled to each other, where each cell has a strong yet lightweight and open structure that can accept uncompacted soil, vegetation roots, utilities, and the like within at least approximately 85-90% of its volume, while also allowing hardscape to be poured or formed thereon. Thus, cell structures allow for hardscape to be integrally formed with the cell structures, without need for an underlying layer of highly compacted soil or other hardscape support.

Block Copolymers and Polymer Modified Bitumen Therefrom

Disclosed herein are linear block copolymers of formula A-B-A′ or A-B*B-A′, wherein blocks A and A′ are polystyrene blocks, block B is a poly(conjugated diene) block and * is a coupling agent having a vinyl content of from 10-60 mol %. The block copolymers have a polystyrene content of from 20-35 wt. %, relative to the overall weight of the block copolymer, and a molecular weight of from 200,000-300,000 g/mol. The block copolymers can be used with a wide variety of asphalt grades, and are valuable for producing homogeneous polymer modified asphalt compositions having an effective combination of performance properties, such as acceptable viscosity, good elastic response to an applied stress, and a low non-recoverable creep compliance. The combination of vinyl content and polymerization technology allows a high solution concentration during polymerization without excessive processing viscosity.
