Question

Three main types of concrete pavements commonly used are Jointed plain concrete pavement (JPCP), ___________________ and continuously reinforced concrete pavements (CRCP).

(a) Jointed reinforced concrete pavement (JRCP)

(b) Jointed reinforced pavement (JRP)

(c) Jointed concrete pavement (JCP)

(d) Reinforced concrete pavement (RCP)

The question was posed to me during a job interview.

Enquiry is from Analysis of Rate of Road Work topic in section Analysis of Rates of Civil Engineering Drawing

Answer 1

The correct choice is (a) Jointed reinforced concrete pavement (JRCP)

For explanation I would say: JPCP’s are constructed with contraction joints which direct the natural cracking of the pavement. These pavements do not use any reinforcing steel. JRCP’s are constructed with both contraction joints and reinforcing steel to control the cracking of the pavement. High temperatures and moisture stresses within the pavement creates cracking, which the reinforcing steel holds tightly together.
