Ⅱ. Purpose and necessity of research and development
In tandem with the announcement of a bikeway-building program which has been underway as a part of recent green environment-related to Saving 4 Big Rivers- coastal bikeway tourism resources development projects, there has been increasing interest in each sector of society regarding pavement method thereof. Furthermore, government said it will invest 1,245.6 billion won until 2018 in building bicycle-only roads spanning 3,114km across the country and will make the most of the existing roads and newly establish the disconnected sections in order to enhance the efficiency of investment.
Accordingly, bicycle networks need to be considered even for material characteristics including beautiful landscape, ranging from new creation of bikeways, change and supplementation of the existing roads into bikeways to natural connection with newly-built sections thereof. In this regard, we planned to develop both semi-rigid pavements for bikeways to be newly applied through this subject and road paving materials for color folium and thin film that can easily change and supplement the existing roads into bikeways, and to develop materials with characteristics that are resistant to salt damage considering the creation of extensive coastal road networks, especially regarding technology to be further developed.
Bikeway needs to have smooth permeability and drainage. Its surface that comes into contact with elastic bicycle wheels has to be semi-rigid or rigid instead of being soft in order to cause no problem driving. It also needs to have proper brittleness considering driving safety and frictional force, especially in general. Given these facts, our developed product comprises organic-inorganic composite materials having both advantages of excellent adhesiveness and color revelation which are characteristics of organic materials and an advantage of high strength which inorganic materials have.
This product that doesn't cause a delamination phenomenon against the existing concrete or asphalt flooring shows excellent adhesiveness that is attributed to the same color folium and thin film as materials of asphalt, causing no separation phenomenon and cracks. The composition made by a patented construction method is so rapid-hardening that it makes pavement completed in a short time(2~3 hours), resulting in short construction period and inexpensive construction cost as an another competitiveness.
Also, this product has more excellent coefficient of static friction of a tire and road surface than that of a concrete or an asphalt road, so it is suitable for road pavement for bicycle and is available for both new pavement and partial pavement. In particular, it is a composition of color polymer cement paste with very strong brittleness and has strong bond strength and high brightness, making it possible to develop various colors of materials, resulting in beautiful presentation of space of cities and roads, and public environmental improvement by offsetting environmental hindrance factors which the existing organic series have with inorganic based.
Also, this product can make the deteriorated part partially repaired as polymer cement paste even without a special manual, make usage period increased, and be judged as helping reduce cost and improve public environments, especially by saving maintenance costs.
