Fields§

§bitumen_content: f64

Bitumen content (% by mass of mix).

§vma: f64

Voids in mineral aggregate VMA (%).

§vfa: f64

Voids filled with asphalt VFA (%).

§air_voids: f64

Air voids (%).

§dynamic_stability: f64

Implementations§

Source§

impl AsphaltMixture

Source

pub fn superpave_12_5() -> Self

Create a standard Superpave-12.5 mix design.

Source

pub fn bulk_density(&self, gmm: f64) -> f64

Computed bulk density (Gmb) approximation: (100 - AV%) / 100 * Gmm. gmm = theoretical maximum density.

Source

pub fn meets_air_voids_criterion(&self) -> bool

Determine if design meets Superpave 4% air voids criterion.
