Maintenance incentives in highway concession contracts
Journal of Transport Economics and Policy, 2007 In most European countries, the private sector has a direct or indirect participation in the construction, overhaul, maintenance, or operation of highways, normally through concession contracts and often with direct payments (tolls) by users. In this context, we construct a model, where demand also depends on road quality, in order to understand the ...

Optimal safety incentives in road concession contracts
European Journal of Transport and Infrastructure Research, 2014 Changes in the roles of the government and the private sector in the provision of public services along with budget constraints are resulting in an increasing use of the concession approach for financing and managing roads. In the last few years, many of these contracts set up incentives linked to bonuses to encourage the concessionaire to render a ...

A Termite‐Inspired Alternative to Cement
Advanced Functional Materials, EarlyView.A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Journal of Civil Engineering and Management, 1998 When implementing any project (not only in building construction), we face a perpetual problem of how to combine three essential and contradictory conditions: price, duration and quality. It is the so-called problem of golden triangle. In competitions

Unusual Swelling Behavior of Hydrogels Modified with Spiropyran as Appendage or Crosslinker
Advanced Functional Materials, EarlyView.Not so innocent after all—spiropyran crosslinkers in methylenebisacrylamide‐crosslinked poly(acrylamide‐co‐acrylic acid) hydrogels increase crosslinking density, but also, counterintuitively, increase swelling. Charge complexation, cooperative chemo‐mechanical effects, and aggregation may explain these observations.
