A fractional factorial design for investigating asphalt concrete production

Description

This is fractional factorial design given in Anderson and McLean (1974) p.256 from an experiment to investigate the effect of controllable variables/factors on the quality of asphalt concrete production.

Usage

data(concrete)

Format

A half fraction factorial design of 16 runs on 6 factors. The 6 factors, each at two levels, included in the design are:

Aggregate gradation (AG)

Categoric factor with levels being fine and coarse.

Compaction temperature (CoT)

Numeric factor with low 250 and high 300.

Asphalt content (AC)

Numeric factor with low 5 and high 7.

Curing condition (CC)

Categoric factor with levels wrapped and unwrapped.

Curing temperature (CuT)

Numeric factor with low 45 and high 72.

Run

Categoric factor with levels 1-16.
