Hello everyone, I need help on getting good and less cost project topics ( will appreciate some links of related journals and other relevant literature) in area of highway engineering or any concrete works relating to highway. More so, anyone in Lagos or Abeokuta who can help in locating or giving links about how to get Recycled concrete aggregate (RCA) should please help me out. Please guys, my email and other means you can reach me are on my signature. Thanks in anticipation.
