Is it possible to build a cheap, distributable kit to test the quality of a newly-laid road? Let me elaborate: in rural economies, the quality of roads has a direct impact on prosperity. Within India, richer states almost always have very good rural roads - helps get produce to market on time, people to hospitals, etc. Unfortunately, road construction is often a corrupt business, and contractors lay poor-quality roads and skim government funds. If we can empower rural communities to effectively do a quality check on the roads laid in their area, it would really help them. They could then file applications under the Right to Information Act to understand why the road was not constructed to mandated quality requirements.
