Construction is underway at the Institute of Advanced Study, where W.S. Cumby will build the Steven Holl-designed Rubenstein Commons later this year. The new Rubenstein Commons building will be constructed on an existing parking lot, necessitating expanded parking options for IAS scholars.
W.S. Cumby superintendent Andrew D’Agostino is overseeing the construction of a new parking lot at IAS. The parking lot will feature porous paving, a green building strategy that manages stormwater and minimizes pollution.
Porous asphalt, also known as pervious, permeable, or open-graded asphalt, is standard hot-mix asphalt with reduced sand or fines and allows water to drain through it. Porous asphalt over an aggregate storage bed will reduce stormwater runoff volume, rate, and pollutants. The reduced fines leave stable air pockets in the asphalt. The interconnected void space allows stormwater to flow through the asphalt and enter a crushed stone aggregate bedding layer and base that supports the asphalt while providing storage and runoff treatment. When properly constructed, porous asphalt is a durable and cost competitive alternative to conventional paving.
